1. Mean:46.7

2. Median: 50

3. Mode:50

Step-by-step explanation:

To find mean, add all of the numbers up, then divide them by how many numbers there are, so in this case:

59+50+49+13+40+46+50+53+58+47=467

there are 10 numbers so you divide by 10.  

467/10=46.7

To find Median, put all of the numbers in numerical order and then go to the start of the list and cross of the first number. Next, go to the end of the list and cross off the last last number. Then, go back to the start and cross the next smallest number off. Do this until you are left with one number, that number will be your median. In this case:

13, 40, 46, 47, 49, 50, 50, 53, 58, 59.

The Median is 50

To find mode, look for duplicates of the numbers in the given list, the number with the most duplicates is 50. There are 2, 50's in this list.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
